ROPE-LOCK.

Speeication of Letters Patent.

Patented Dec. 21, 1.1115.

Application led April 7, 1915. Serial No. 19,633.

To all Iwhom t may concern.'

Be it known that 1, JACOB C. N. Wis'rnN- DA1-IL, a. citizen of the United States of America, and a resident of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Rope- Locks, of which the following is a specification.

This invention relates to improvements in rope locks and similar devices.

The object of the invention is to provide a rope lock or rope clamp of generally i1nproved construction.

@ne object of the invention is to provide a rope lock constructed entirely of metal wire or similar material which may be bent easily into the desired shape.

Another object is to provide an efficient rope clamp adapted to be manufactured at a low cost.

Still another object of the invention is to provide a rope lock of relatively flat design so that it may be conveniently carried about.

Other objects will appear as this specification proceeds, while reference is had to the accompanying drawings showing the preerred form of my invention and in which- Figure 1 is a plan View of a rope lock embodying my invention. Fig. 2 is an edge View, the rope being removed at the one end of the lock. Fig. 3 is an edge view illustrating the use of the rope lock when the rope is to be slackened with parts broken away, and Fig. 4 shows a modification.

Rope locks :tor locking a rope in a given adjusted position are used mostly in connection with clothes lines, on boats, for tents, with guy ropes and the like, when the rope generally forms a loop or has two running parallel lengths. I do not wish, however, to be limited in the application of my improved rope lock, nor in its` construction otherwise than required by the scope of the appended claims.

1n carrying out my invention, I employ a bifurcated body member 5 comprising the two arms 6, 6 each of which is bent to form an eye 7.

8 is an eye or loop preferably centrally disposed with relation to the arms 6. As shown, the clamp body is bent from one piece of wire and the loop or eye 8 serves as a means for securing the one end 9 of the rope 10.

11 is a clamping lever formed as a closed oblong loop provided with eyes 12, 12 or which is a locking member formed in the shape or' a flat S in two planes at right angles to each other as seen from Figs. 1 and 2.

It will be noted that the clamping lever 11 is formed out of one piece of wire, the ends 17, 17 of which are bent around the loop portions 15, 15.

Fig. 1 shows the use of the rope lock when there is a pull or strain upon the rope which strain or pull is indicated by the arrows 18, 18. 1t is then apparent that the free end 14 oi' the rope is locked or clamped at 19 in the clamping lever 11 by the rope 10 and that the harder the pull is on the rope, the tighter it is clamped or pinched at 19 in the sharp bend around the locking member 16. Slight adjustments to shorten the length of the rope may be made by relaxing the one end o1 the rope as shown at 2O in dotted lines when it is obvious that the tree end 1e may be pulled through the eye 13 to shorten the loop of the rope. But for 'quick and large adjustments to either shorten or lengthen the rope, the lever 11 is swung or tipped upon its pivots 12, 12 to a positionl about as shown in Fig. 3 where it will be seen that the rope slides easily in either direction, being guided and straightened by the locking bar or member 16. The rope is quickly locked by movingthe lever 11 into its position within the clamp body 5, when a quick pull on the rope will again clamp the free end 1-1 and lock the rope.

1 have found a rope lock constructed according to the drawing and the foregoing de scription to work perfectly and to provide instantly operated means Jfor quickly locking the rope in any adjusted position.

1t will be observed that the clamp lever 11 lies nearly flat within the clamp body and that the operation and construction of the rope lock is very simple and eliicient.

1n case where it is desired to secure the rope lock to an object such as a ring in a hitch post or when used with tents or sails, e hook 25, as shown in Fie'. 4, may be provided or used Without departing from the principle of the looking` feature.

claim:

l. A rope lock comprising a body member, a clamping member pivoted to seid body member and a looking` bar formed integral with said clamping member Within the latter.

2. A rope lock,comprising` a body member, e elampinp; member pivot-ed to said body member, a locking` ber formed integral With said clamping member within-the latter and a. guiding means for the rope formed on said clamping,` member adjacent the one end thereof.

3. A rope look comprising a body member, e clamping member formed as an oblong` closed loop piyoted on said body member and movable Within the latter, a looking member formed kWithin said clamping; member longitudinally thereofand a rope l@guiding' eye formed on said Clamping; member adjacent the one end thereof.

'-il. A rope lock comprising` a biiurcated body member, an eye for securing the rope formed integral with said member, a Clamping;` member forming,` a Closed loop pivoted to the bifureated portions of said body mem- ;v

ber and movable Within the same, a leeking' bar formed integrally with Said clamping' member longitudinally thereof and a rope guiding eye on said clamping); member adjacent the one end of the said lookingbar. 1'

A rope lool; comprising; a body member consisting' of a centrally disposed eye and two arme, one on each side of said eye` a clampingmember comprisinga closed loop, pivoted in the free ends of the said two arms within the same and a locking and rope guiding' bar within the said loop Jformed integrally therewith.
